Contrary to popular belief, losing weight isn’t always synonymous with improved health.
A recent study from Anglia Ruskin University (ARU), published in the BMJ journal Heart, has uncovered surprising risks associated with extreme weight changes, particularly for individuals with cardiovascular disease.
The risks of weight fluctuation
The study analyzed data from 8,297 participants enrolled in the UK Biobank study over 14 years. Findings revealed that weight fluctuations, whether gain or loss, can significantly increase mortality risk in obese individuals with heart conditions.
Key findings include:
Gaining more than 10 kg tripled the risk of cardiovascular death and nearly doubled all-cause mortality compared to maintaining a stable weight.
Losing over 10 kg was linked to a 54 percent higher risk of death from any cause.
Factors such as higher BMI, smoking, and previous alcohol use increased the likelihood of significant weight gain, especially among younger people.
Why stability matters
While losing weight is often recommended for obesity, the study suggests that drastic changes can be detrimental, particularly for those with heart issues. Rapid weight loss may result in muscle mass loss, nutritional deficiencies, or metabolic stress, all of which can strain heart health.
Professor Barbara Pierscionek, co-author of the study, stressed that maintaining a stable weight, even within the obese range, is essential for reducing mortality risk among heart patients.
Caution with weight-loss strategies
With obesity rates doubling in England since 1993 and new weight-loss drugs gaining popularity, experts urge caution for those with cardiovascular disease. Dr. Jufen Zhang, lead author of the study, advises that at-risk individuals should only pursue weight loss under medical supervision.
Instead of extreme diets, gradual lifestyle changes focusing on balanced nutrition and regular activity are recommended. Remember, long-term heart health is not just about numbers on the scale but maintaining stability and sustainable habits.
